SPINNING-RING.

Application filed October as, 11915.

To all whom it may concern:

e it known that I, JAMES K. LANNING, a citizen of the United States, and a resident of Fall River, county of Bristol, and State of Massachusetts, have invented an Improvement in Spinning-Rings, of wh ch the following description, in connectlon with'the accompanying drawings, is a spec1- fication, like characters on the drawings representing like parts; 4 4 I This invention relates to spinning rlngs and particularly to stationarily mounted spinning rings. I f e In order that'the principle of the nvention may be readily'understood, I have represented an embodiment thereof in the accompanyingdrawing, wherein- Figure 1 is a plan view of the preferred embodiment of my invention;

Fig. 2 is alvertical central section thereof upon an enlarged scale; ai'1d Fig.3 isa' -vertical section of a part of th ga e An important object of my invention is to provide a spinning ring of such construcmaterialreduction in the friction of the traveler thereon. Further objects of the invention willbes'et forth hereinafter So far asv I am'aware, no successful spinning ring has been produced excepting by" forging, which is machined down and thenflcase-hardened and polished. The 'r'ing herein disclosed has said characteristics, and is'there fore of tru'e circular form, a desideratum the useof sheet metal. The preferred form of traveler is one of mild steel, caseharden ed. Economical commercial production requires all travelers to be symmetrical in form and double-ended, so that they may be placed upon the ring without any requirement that one end or the other be made the inner end. In accordance with the preferred embodiment of my invention, I have provided rings peculiarly adapted to receive travelers of such double-ended formation, though my invention isnot limited to the use of such a traveler. I In the figures, I have indicated the preferred embodiment of my invention.

Referring more particularly to Figs. 1 and 2, the basal portion of the ring is indicated at 2 and the upright body at 3, the traveler flange being generally indicated at 11. I have herein represented the inner edge 12 as blunt and of considerable vertical not secured through Specification of Letters Patent.

extent and have shown the outer edge 13 as thin and as presenting substantially a single circumferential line. Preferably the top surface 14 of said flange is slightly concave. At some suitable point between the inner and outer edges 12 and 1.3, and

preferably at the point indicated, I provide I an annular ridge l5 extendingsli htly above the top surface of said flange. referably said ridge is positioned. between the body 3 and the outer edge 13.,

The function of the annular ridge 15 is to. reduce the friction between the traveler and the body of the flange, or between forelgn matter upon the traveler an motion of the traveler heretofore referred to, contact is made by the traveler, not with the entire top surface. of the traveler flange, but with the annular ridge 15. of my invention, the said ridge 15 might be slightly interrupted at one or more points itis preferably'continuous and of uniform height throughout, thus insuring theleast friction between it and the ring 16., While I have herein represented the an nular ridge 15 as providedupon a traveler flange having a thin outer edge, it is to be clearly understood that my invention is not limited thereto, inasmuch as be formed upon other types of..traveler flanges, as, for example, those having a blunt outer edge, and inasmuch as in either case between the traveler flange and the ring is reduced by the employment of such ridge.

'iIn the illustrated form of my invention I reduce the friction between the traveler or foreign matter thereon and the traveler flange of the ring.

, raving reference to that form of my invention shown-in Figs. 1 and 2, it is my belief that the thin outer edge of the traveler flange assists in a rapid dissipation of heat generated in the ring incident to the spinnlng operation. Moreover the provision of thethin outer edge permits the mor ready application of the traveler thereto.

Obviously the lower flange of the ring may be of the same construction as the upper flange, thereby making the ring reversible.

In Fig. 3, I have shown in detail a part of the ring. The top surface of the ring i provided with annular ridge 18 havand said, In the lrregularor up=and-down said ridge may a of said traveler flange is preferably blunt. The inner edge 20 is also blunt.

Having thus described one illustrative em bodimentof my invention, I desire it to be understood that although specific terms are employed, they .are used in a generic and descriptive sense and not for purposesof limitation, the scope ofthe invention being set forth in the following claims.

Claims: l. A spinning ring provided witha traveler flange having its upper surface in the form of an annular trough, the upper limits of the inner and outer edges of said flange being in different horizontal planes and a friction reducing elevation between said inner and outer edges. 2. A spinning ring provided with a traveler flange, the upper surface whereof, between its inner and outer edges, is below the upper limit of said edges, whereby an annular trough or depression is provided, the

upper limits of the inner and outer edges of said flange being in different horizontal planes and a friction reducing elevation between said inner and outer edges.

3. A Spinning ring provided with a traveler flange having blunt inner and outer edges extending above the intermediate surface of the flange and also having a frietional reducing elevation between said inner and outer edges.

4-. A spinning ring provided with a traveler flange having blunt inner and outer edges, the inner edge being of the greater vertical extent, the top surface of said flange between said edges being below the upper portions of said edges and also having a frictional reducing elevation between said inner and outer edges.

5. A spinning ring provided with a traveler flange having a substantially annular ridge upon its upper surface and constituting a friction reducing elevation between the inner and outer edges of said flange, said upper surface, excepting for said ridge, being below the upper limits of the edges of the traveler flange.

6. A spinning ring provided with an upstanding body and a traveler flange, the upper surfaceofthe latter being recessed and also provided with a substantially annular ridge between said body and the outer edge of said flange. 1

7 A spinning ring provided with a traveler flange having a concaved upper surface and also having elevated friction-reducing means upon said upper surface between the inner and the outer edges of the ring.

8. A spinning ring provided with a traveler flange having a dished upper surface and also having an elevated friction-reducing formation upon its upper surface between the inner and the outer edges of the ring. i i

9. A spinning ring provided with a trav, eler flange, the upper-surface of which is concaved and is provided with an annular ridge spaced from the edges of the ring.

10. A spinning ring provided with a traveler flange, the upper surface whereof is concaved, said upper surfaceibeing provided with an annular ridge betweenthe. inner and the outeredges of the ring,

11. A spinning ring provided with a traveler flange having an annular concavity upon its upper surface between its inner and outer edges, andhaving an annular'ridge upon said uppersurface between the inner and outer edges of the ring, at least one of.

said edges extendingat least as-high assaid ridge. i

12, A spinning ring provided with a trav eler flange having an annularly concaved upper surface between its inner and outer edges, said surface being provided with friction reducing means extending above the base of said concavity between the inner and outer'edges of the ring, at least one of said edges extending at least as high as said fric tion reducing means. 13. A spinning ring provided with a traveler flange whose upper surface annularly concaved, said upper surface being provided with an annular ridge whose top is below. the level of atleast one of the edges of the traveler flange. v 1 i g 14:. A spinning ring provided witha traveler flange having an inneredge and alower outer edge, the upper surface ofsaid flange being annularly concaved, said upper surface having an annular ridge, the top whereof is below the top of theinner edge of said traveler flange.

In testimony whereof, I havesigned my name to this specification, in the presence of two subscribing witnesses.
